WELDING IN STICK MODE

5. Turn the power switch to “ON”.

 

Return to Master TOC

1.Put the electrode holder and cable quick connect plug into the electrode output receptacle. Turn clock- wise until tight. Connect the work clamp to the work piece.

2.Set the TIG/STICK switch to “STICK”.

3.Set the Polarity Switch to the weld mode desired for the type of electrode being used (most commonly DC+).

4.Place the electrode in the electrode holder.

WARNING

6.Adjust the Current Control to the desired amps.

7.Strike an arc and weld.

NOTE: When the TIG/STICK switch is set to “STICK” the output is always on when the power switch is on. A remote control has no effect on the welding current and the gas flow and high fre- quency TIG arc starter are disabled.
